Three-dimensional printing, also known as additive manufacturing, is the process of using additives to form solid 3D objects of virtually any shape from a digital model. This is achieved using specially formulated additives, such as plastics, that are formed into successive layers of material typically laid down on a platform in different shapes. 3D printing is uniquely distinct from a more traditional 3D sculpting technique, which relies on the removal of layers (subtractive manufacturing)...
